Answer:

The first one is D and the second one is B

Step-by-step explanation:

The first is D because the volume of a cylinder is v = π (pi) times the radius squared times the height of the cylinder.

so (π)(16^2)(7) =5629.73 ft^3

Then 1 ft^3 is = 7.5 gallons of water, so you multiple 5629.73 by 7.5 and round. Which gets you 42223

A recipe calls for 2 cups of flour to make 24 cookies. Write and solve a proportion to find how much flour is needed to make 54
horrorfan [7]
For the answer to the question above,
when you put it into a proportion it would be 2/24 = x/54  
multiply 2 and 54 which equals 108 
and multiply 24 and x which equals 24x
so you have 24x=108       divide 24x by 24 so you have x standing alone but what you do to one side you have to do to the other so divide 108 by 24 and get 4.5 which is 4 1/2 cups of flour. 
So the answer is<span> 2/24 = x/54; x = 4 1/2 cups</span>
